After a number of experiments this weekend, I can say that the graphical installer is not COMPLETELY broken, It merely contains a fatal flaw.
It will only work if an LV file system is mounted on /, and optionally on /home. It will also allow an LV configured as swap. If those conditions are met, the / (root) partition will be mounted on /target and the /boot (a separate physical partition on the drive) and /home partitions will be mounted under /target/boot and /target/home respectively. In that configuration, the installation will proceed successfully and the OS will be installed to the drive. Any attempt to use any other mount point will fail. The / (root) partition will be mounted under /tmp/tmp.LARGE_RANDOM_NUMBER and the other partitions will remain unmounted. Nothing will be written to the drive. On the chance that there was an artificial limit on the number of mount points, I tried to install to a configuration of /boot (sda1), and LVs of / (root), swap and /var (instead of /home). The installation failed as described above. The 64-bit Ubuntu-desktop image suffers the same flaw, I can only assume that all of the desktop images share this flaw. Note that the 64-bit ubuntu-server image works as expected. It does NOT share this flaw. I believe that at the very least, this flaw should be noted in the release notes. As it stands, I see only two ways to upgrade my Kubuntu 14.04 system: 1) Install ubuntu server and then attempt to install KDE and the other desktop apps on top of that. 2) Install Kubuntu on a separate drive and then do a fork-lift upgrade by migrating the system from that drive to my original system. Neither option is very appealing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1719053 Title: Kubuntu 64-bit 16.04.3 installer is broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1719053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
